This chapter describes the breakout mode on the router, the guidelines and restrictions that apply to the breakout mode, the tasks for configuring the breakout on a port and removing the breakout configuration, and the partial breakout feature for 400G optics on Cisco 8010 Series routers.
Breakout mode
This topic describes how the router supports transmission of traffic in the breakout mode, which enables a 40 Gigabit Ethernet port to be split into four independent and logical 10 Gigabit Ethernet ports on supported 40G modules.
Configuration guidelines and restrictions for the breakout mode
This topic lists the guidelines and restrictions that apply when you configure the breakout mode.
Configure the breakout on a port
This topic describes how to configure the breakout mode on an optics controller of a port so that the router splits the port into four independent and logical 10 Gigabit Ethernet subports.
Remove the breakout configuration
This topic describes how to remove the 4x10 breakout configuration from an optics controller of a port so that the router restores the port to its original 40 Gigabit Ethernet operating mode.
Partial breakout for 400G optics on Cisco 8010 Series routers
Explains how the partial breakout feature for 400G optics enables flexible port combinations and maximizes hardware utilization on Cisco 8010 Series routers.
